Question

A certain number was increased 5 times, then decreased by 3, then halved. The result was 0.3 less than the original number. What was the original number?

Answer 1

Explanation:

x=(5x/3)2)-0.3. 5x/6-0.3=x. x=-1.8

Answer 2

If increased 5 times means x5, then the answer is 0.72 as 0.3 x 2= 0.6+3= 3.6 x0.2= 0.72
